For example, zh_TW is an alias to zh_Hant_TW. Without aliases, zh_TW would fall back to zh (which is incorrect). With aliases loaded, zh_TW will fall back properly to zh_Hant_TW.

@javiereguiluz all our icu data providers use an entry reader to actually read icu data from (currently) json files we bundle with the intl component. The entry reader already supports handling aliases. However, we never told it to use any aliases. Now we do :) |

…zal) This PR was squashed before being merged into the 2.7 branch (closes #26452). Discussion ---------- [Intl] Load locale aliases to support alias fallbacks | Q | A | ------------- | --- | Branch? | 2.7 | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | #21457 | License | MIT | Doc PR | - For example, `zh_TW` is an alias to `zh_Hant_TW`. Without aliases,` zh_TW` would fall back to `zh` (which is incorrect). With aliases loaded, `zh_TW` will fall back properly to `zh_Hant_TW`. Judging by git history this has never worked. ```php \Locale::setDefault('zh'); dump(Intl::getRegionBundle()->getCountryName('AD')); \Locale::setDefault('zh_TW'); dump(Intl::getRegionBundle()->getCountryName('AD')); \Locale::setDefault('zh_Hant_TW'); dump(Intl::getRegionBundle()->getCountryName('AD')); ``` Before: ``` "安道尔" "安道尔" "安道爾" ``` After: ``` "安道尔" "安道爾" "安道爾" ``` All tests are passing, including those from the `intl-data` group.
